Elios

From BoardGameGeek:

Elios is an abstract wooden game you play in 2 steps. Goal of the game: Be the first player to get rid of all your sticks. Each player receives some colored sticks at the beginning of the game (the number varies with the number of players). First, all the players use their sticks to create sets of 1 to 3 sticks in front of them. Then, upon their turn, players will do one of the following actions: play a full set on the Sun or place a disc on the Sun or divide one of their sets into 2 sets. Of course to play a set, you need to follow certain rules: all the sticks need to be at the same level the set can't be at a higher level than the disc in the middle. The first player to play all their sticks on the Sun wins the game. In a 4 player game, you can play in teams. -description from the publisher
